HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 429, 234, 43 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 429, 234, 43 is 1 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.
Consider we have numbers 429, 234, 43 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b
Highest common factor (HCF) of 429, 234, 43 is 1.
HCF(429, 234, 43) = 1
HCF of 429, 234, 43 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 429, 234, 43 is 1.
Highest Common Factor of 429,234,43 is 1
Step 1: Since 429 > 234, we apply the division lemma to 429 and 234, to get
429 = 234 x 1 + 195
Step 2: Since the reminder 234 ≠ 0, we apply division lemma to 195 and 234, to get
234 = 195 x 1 + 39
Step 3: We consider the new divisor 195 and the new remainder 39, and apply the division lemma to get
195 = 39 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 39, the HCF of 429 and 234 is 39
Notice that 39 = HCF(195,39) = HCF(234,195) = HCF(429,234) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 43 > 39, we apply the division lemma to 43 and 39, to get
43 = 39 x 1 + 4
Step 2: Since the reminder 39 ≠ 0, we apply division lemma to 4 and 39, to get
39 = 4 x 9 + 3
Step 3: We consider the new divisor 4 and the new remainder 3, and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 39 and 43 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(39,4) = HCF(43,39) .
